It'd be even cooler in two-ways, where using the switch on the one side of the room causes the other switch to match. Not sure why this isn't available either.
It's kind of like a joy stick, so in a neutral center position and you flick it momentarily up or down from center to ask for on or off. You have to learn not to lift and hold for too long, because that is how to get it into a very primitive reconfiguration mode. As I recall, you can reconfigure the LED and maybe its behavior on power restoration.
I configured mine so the LED is on when the light circuit is on, to show me the status of an exterior light on the other side of an opaque door. But, I think the default is the inverse so it acts a bit like a night light to locate the switch in the dark. Of course, it's a hideous blue as is the modern fashion.
I linked it to an existing alarm system to set some rules like turning on and off around dusk and dawn periods and turning on in response to camera-based motion/people.
I've ordered some Inovelli switches which do this and have an RGB LED if I need a state status indicator.
Sadly it was very expensive and also locked down to their private cloud. The company went bust and took everyone's 'smart' homes with them.
